- Now have students test their observation skills. Have students stand up.
- Have students pick a partner and face each other for 15 seconds. Tell them to observe each other.
- Now have them stand back to back and change something about their appearance. (examples: change a ring to another finger, roll up a sleeve, push down a sock, etc.)
- Call time and have students face each other. Each partner guesses what the other has changed.
- Have the students do this two or three times.
- Students sit back down, open their notebooks and answer these questions (have on overhead or board).
- What did you want to find out?
- What changes were made by your partner?
- What did you do to discover your partner’s changes?
- Discuss and then have students write down the five steps of an experiment.
- Have students write a brief summary under each step and discuss.
